Abstract

(57) [Summary] [Purpose] To prevent iron ore from adhering to the buffer plate 6 and becoming a one-sided load when loading onto a belt conveyor after transfer. [Structure] The iron ore adhering to the buffer plate 6 is shaken off by an electromagnetic hammer 13 attached to the back side of the buffer plate 6 against which the iron ore dropped into the chute 1 for guiding the load collides. [Effect] Since iron ore does not adhere to the buffer plate 6, there is no possibility that the belt conveyor will have one load after transfer, and there is no need to remove the adhered iron ore.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

A system for transferring belt conveyors that transport large quantities of iron ore, etc. Regarding ute.

0002

[Conventional technology]

Used for transfers on belt conveyors that transport large quantities of iron ore, etc. In a conveyor chute, the bell after transfer at the outlet of the conveyor chute There was a problem in that when loading onto the conveyor, the load would be one-sided. This situation is shown in Figure 2. show. Figure 2 is a vertical sectional view of the side near the conveyor chute according to the conventional technology. be. In the figure, 1 is a conveyor chute. 2 is an input port. 3 is exclusive It is the exit. 4 is the iron ore to be input. 5 is a belt conveyor. 6 is It is a buffer plate. 7 is iron ore attached to the buffer plate. 8 is beltco after transfer This is iron ore loaded onto a ship. 12 is a head pulley.

0003 Here, iron ore 4 is fed into conveyor chute 1 by belt conveyor 5. It will be done. The traveling speed of the belt conveyor 5 is 100 m/min to 150 m/min. Therefore, the iron ore 4 thrown in falls along the arrow 9 and collides with the buffer plate 6. It then falls along arrow 10, collides with conveyor chute 1, and then It falls along mark 11. Iron ore 7 gradually adheres to and grows on the buffer plate 6.

0004 The falling direction shown by arrow 10 gradually shifts toward the input port, and finally the container It collides with the bear chute 1 and then falls along the arrow 11. and Gradually, when the iron ore 8 is loaded onto the belt conveyor after transfer, it becomes a single load, and the iron ore 8 This causes the belt conveyor to meander after being transferred. Therefore, it is attached to this buffer plate 6. A worker is pushing down grown iron ore 7 with a long iron crowbar. this work The number of man-hours required reached a considerable value.

[0005] A proposal regarding a conveyor chute for transferring between high-speed belt conveyors, etc. This is disclosed in Japanese Utility Model Application Publication No. 64-50209. In other words, from the input port to the discharge port A chute is formed to guide the load into the chute, and the output end of the belt conveyor is inserted into the input port. Covering the load from the outside along the parabolic orbital surface of the load dropped from the unloading end and discharging the load as described above. A computer characterized by being provided with a guide member that guides the load on the axis of the mouth and allows it to fall. "Bear Shoot" has been proposed.

[0006] Figure 3 shows the vicinity of the conveyor chute according to the technology proposed in the above publication. It is a vertical sectional view of the side surface. In the figure, 1 is a conveyor chute. 2 is a throw It is the entrance. 3 is a discharge port. 4 is the iron ore to be input. 5 is belt control Bear. 6 is a buffer plate. 8 is loaded onto the belt conveyor after transfer. iron ore. 12 is a head pulley. 14 is the position adjustment rod for the buffer plate. be.

[0007] When iron ore gradually adheres to the buffer plate 6 and grows, the belt conveyor after transfer When loading the iron ore 8, the iron ore 8 becomes a one-sided load, and after the transfer, the iron ore 8 is meandering to the belt conveyor. Therefore, the position of the buffer plate 6 should be moved back to prevent the iron ore 8 from becoming a one-sided load. Ru.

[0008]

[Problem that the idea aims to solve]

However, by retracting the buffer plate of the conveyor chute mentioned above, iron ore According to the device that prevents unbalanced loads, it is always difficult to load onto the belt conveyor after transfer. During loading, iron ore 8 became one load, causing meandering of the belt conveyor after transfer. It is necessary to monitor whether there is a problem and adjust the position of the buffer plate. Furthermore, this loose A worker uses a long iron crowbar to push down iron ore that has grown on a plate. is necessary.

[0009] This idea was devised in view of this situation, and eliminates the need for the above-mentioned work and improves passenger comfort. The aim is to provide a device that can prevent belt conveyor meandering after transfer. target

0010

[Means to solve the problem]

The belt conveyor chute according to this invention is a system that guides loads from the input port to the discharge port. form a conveyor belt, and insert the output end of the belt conveyor into its input port. In the parabolic trajectory drawn by the load dropped from the delivery end, the load collides with the In the chute of a belt conveyor equipped with a shock plate, an electric current is used to vibrate the buffer plate. It is characterized in that a magnetic hammer is attached to the buffer plate.

[0011]

[Effect]

The chute of the belt conveyor according to this invention has a shape in which the load dropped from the delivery end is drawn. An electromagnetic hammer is attached to the buffer plate that the load collides with in a parabolic trajectory to generate vibrations. The deposits can be removed by rubbing.

0012 This ensures that the load is always evenly distributed from the center of the belt conveyor to both sides after transfer. Ru.

[0013]

【Example】

FIG. 1 shows a chute of a belt conveyor according to an embodiment of the present invention. Figure 1 is the main idea. FIG. 3 is a vertical cross-sectional view of the side near the chute of the proposed belt conveyor. In the figure, 1 is a conveyor chute. 2 is an input port. 3 is a discharge port. 4 is a throw This is iron ore that is imported into the country. 5 is a belt conveyor. 6 is a buffer plate. 8 is This is iron ore loaded onto the belt conveyor after transfer. 12 is the head pulley - is. 13 is an electromagnetic hammer. 14 is a position adjustment rod for the buffer plate.

[0014] The electromagnetic hammer 13 applies four vibrations of vibration to the buffer plate 6 approximately once every 10 minutes. Ru. This vibration has a period of approximately once per second. Electromagnetic hammer used in this example -13 has a capacity of 0.6kW. This vibration exerts a shocking effect on the buffer plate 6. As a result, the iron ore that gradually adheres to and grows on the buffer plate 6 is knocked off. It will be done. For this reason, the surface of the buffer plate 6 is always free of deposits, and the iron ore 4 to be introduced is indicated by the arrow 9, collides with the buffer plate 6, then falls along the arrow 10, and this The falling direction shown by the arrow 10 is always toward the center of the outlet 3. The result The iron ore 8 is loaded evenly on both sides from the center of the belt conveyor after transfer. As a result, iron ore 8 becomes a single load when loading onto the belt conveyor after transfer. It does not cause meandering of the conveyor belt.

[0015]

[Effect of the idea]

With this idea, the iron ore is distributed evenly from the center of the belt conveyor to the left and right after transfer. It does not cause the belt conveyor to meander when loaded, and it grows by adhering to the buffer plate. There is no need for workers to push down the iron ore with an iron crowbar.

[0016] Furthermore, it is also necessary to change the position of the buffer plate to prevent meandering onto the belt conveyor after transfer. lost.
